UNITED STATES FRANK BARCLAY, OF AURORA, ILLINOIS.

IM PROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 115,014, dated May 23,1871.

I, FRANK BARGLAY, of the city of Aurora,

in the county of Kane and State of Illinois,

the pipe and sleeve are not in section; Fig. 2,

a horizontal section on line any of Fig. 1; Fig. 3, an enlarged detail,showing the parts a b in a horizontal section.

My improvements are, primarily, designed to be used in open stovesburning either soft or hard coal and consist in providing airpassagesbehind the fire-brick, and in the mode of regulating the draft byproviding the smoke-pipe with one or more slots, closed or opened by arevolving sleeve.

In the drawing, A represents an open grate for the reception of fuel. ais a corrugated back; 12, a lining of fire-brick or other suitablematerial. The back a, may be plain, and the back side of the fire-brickor other lining b may be grooved or corrugated vertically; or tubesextending to the bottom may be placed between them. Air-passages arethus provided between a and b, into which air will enter at the bottom,and will pass out, highly heated, over the top of b and mingle with theflame and smoke, greatly aiding combustion. B is a flame-chamber, fromwhich there is an opening, f, for the passage of the smoke and heat intothe radiating-chamber O. D is the.

smoke-pipe, which extends down nearly to the bottom of the chamber 0,and in its lower part are one or more slots, 0, which it is best to makesomewhat spiral. d is a revolving sleeve, in which are one or moreslots, 6, Figs. 1, 2, correspondin gin number with those in the pipe.These slots in the sleeve need not be may be wholly open, or partlyopen, or wholly closed, according to the position of the sleeve d. Whenwholly closed the smoke must all go to the bottom of the radiatingchamber (hand will there enter the pipe.

'One or more air-pipes, g, are located in the chamber 0, into which coldair passes from beneath the stove and out at the top. E is an opening inthe top, and h an opening beneath the grate, for cleaning theradiating-chamber, both of which are closed when not in use. A slide, 6,is placed below the grate, covering open in gs into the chamber G, whichmay be opened when the grate is shaken so that the dust from the asheswill be drawn into the chamber O. m is an ash-pan.

A series of holes may be made in the pipe D instead of the slot shown,so arranged that they can be opened or closed by the sleeve. The slotsin the pipe may be vertical and those in the sleeve spiral, or both maybe vertical, and so arranged that the one in the pipe will be graduallyclosed, and at the top first, by turning the sleeve.

I am aware that a sleeve having a vertical movement, and without slots,has been used 'for regulating the draft.

With my improvement a much more com pact stove can be made, and otheradvantages attend its use.

What I claim as new is as follows:

1. The revolving sleeve dprovided with one or more slots, 6, incombination with the pipe 1) provided with one or more inclined slots oropenings, 0, substantially as and for the purposes specified.

2. The combination of the revolving sleeve d provided with one or moreslots, with the pipe D provided with one or more inclined slots oropenings, 0, the radiating-chamber O, flame-chamber B, and fire-grate A,substantially as specified.

3. The combination of the corrugated back a and lining b, constructed asdescribed, with the chamber B, radiating-chamber (J, and slotted pipe D,substantially as and for the purposes specified.
